ad5869ac6c Remove unused functions from isc_thread API
The isc_thread_setaffinity call was removed in !5265 and we are not
going to restore it because it was proven that the performance is better
without it.  Additionally, remove the already disabled cpu system test.

The isc_thread_setconcurrency function is unused and also calling
pthread_setconcurrency() on Linux has no meaning, formerly it was
added because of Solaris in 2001 and it was removed when taskmgr was
refactored to run on top of netmgr in !4918.

2bf7921c7e Update the copyright information in all files in the repository
This commit converts the license handling to adhere to the REUSE
specification.  It specifically:

1. Adds used licnses to LICENSES/ directory

2. Add "isc" template for adding the copyright boilerplate

3. Changes all source files to include copyright and SPDX license
   header, this includes all the C sources, documentation, zone files,
   configuration files.  There are notes in the doc/dev/copyrights file
   on how to add correct headers to the new files.

4. Handle the rest that can't be modified via .reuse/dep5 file.  The
   binary (or otherwise unmodifiable) files could have license places
   next to them in <foo>.license file, but this would lead to cluttered
   repository and most of the files handled in the .reuse/dep5 file are
   system test files.

45c55b1e7e Add isc_trampoline API to have simple accounting around threads
The current isc_hp API uses internal tid_v variable that gets
incremented for each new thread using hazard pointers.  This tid_v
variable is then used as a index to global shared table with hazard
pointers state.  Since the tid_v is only incremented and never
decremented the table could overflow very quickly if we create set of
threads for short period of time, they finish the work and cease to
exist.  Then we create identical set of threads and so on and so on.
This is not a problem for a normal `named` operation as the set of
threads is stable, but the problematic place are the unit tests where we
test network manager or other APIs (task, timer) that create threads.

This commits adds a thin wrapper around any function called from
isc_thread_create() that adds unique-but-reusable small digit thread id
that can be used as index to f.e. hazard pointer tables.  The trampoline
wrapper ensures that the thread ids will be reused, so the highest
thread_id number doesn't grow indefinitely when threads are created and
destroyed and then created again.  This fixes the hazard pointer table
overflow on machines with many cores. [GL #2396]

46919579bb Make isc_thread_join() assert internally on failure
Previously isc_thread_join() would return ISC_R_UNEXPECTED on a failure to
create new thread.  All such occurences were caught and wrapped into assert
function at higher level.  The function was simplified to assert directly in the
isc_thread_join() function and all caller level assertions were removed.

1a69a1a78c Megacommit of dozens of files.
Cleanup of redundant/useless header file inclusion.

ISC style lint, primarily for function declarations and standalone
comments -- ie, those that appear on a line without any code, which
should be written as follows:
   /*
    * This is a comment.
